Injection drug use (IDU) was one of the earliest risk factors identified for acquisition of HIV infection...This project was designed around an interprofessional and cross-cultural student collaboration to assess an important social/behavioral risk for HIV acquisition. Since there is very little work in the space of IDU in sub-Saharan Africa, it required heightened sensitivity among the students to work within the medical/social/behavioral context in a foreign country. Addressing people who inject drugs requires multidisciplinary collaboration across various professions, including medical, nursing, social, pharmacologic, and legal.
